Here's a classical example:

I can not prove it, but from the comments and messages I have received from Diggers I believe there are a couple of reasons I am buried. First, Geeks are generally progressives and I am a conservative, albeit of a libertarian mindset—but they don't understand that. Second, like many Geeks, their sexual development is rather stunted—and are quite misogynistic and homophobic in an adolescent sort of way. So they do not like their progressive viewpoints ridiculed by an intelligent conservative lesbian.

One of the reasons that I don't bother with providing Digg links on my posts.
